Explanatory Notes Glossary Abbreviations Data Cubes (I-Note) Data Source	EXPLANATORY NOTES INTRODUCTION 1 This publication presents information relating to the criminal jurisdiction of the Higher (Supreme and Intermediate) and Magistrates' Courts in each state and territory and the Children's Courts for all states and territories except New South Wales (NSW) and the Australian Capital Territory (ACT). The criminal jurisdiction of the courts includes the trial and sentencing of persons and organisations charged with criminal offences. This information is sourced from the national Criminal Courts collection produced by the Australian Bureau of Statistics (ABS) with the cooperation of the states and territories. 2 The aim of the Criminal Courts collection is to provide comparable statistics for the states and territories and for Australia on the characteristics of defendants dealt with by the Criminal Courts. This includes information on the offences and sentences associated with those defendants. Refer to paragraphs 44-47 of the Explanatory Notes for further information. 3 In order to ensure consistency between the states and territories, the statistics have been compiled according to national standards and classifications. 4 Due to differing scope and counting rules the data in this publication may not be comparable to data published in other national and state/territory publications. 5 Given the high degree of conceptual complexity in the operation of the courts systems in Australia, and the variation in the capacity of the states and territories to supply statistical information, a staged approach has been adopted for the development and conduct of the Criminal Courts collection. 6 This publication presents results from several development stages of this collection. Information relating to criminal cases heard in the Supreme and Intermediate Courts has been available since the mid 1990's. Information about defendants finalised in the Magistrates' Courts and their characteristics, including offences and sentences for defendants who were finalised by adjudication is available from 2003-04 onwards. Information about defendants finalised in the Children's Courts and their characteristics, including offences and sentences for adjudicated defendants is available as experimental data (Refer Appendix 1). DATA SOURCE 7 National statistics are derived from data about each defendant provided to the ABS by the state and territory agencies responsible for courts administration. This includes defendants processed in the Higher, Magistrates' and Children's Courts. The ABS receives data directly from these agencies in all states and territories except for Queensland (where data are supplied via the Office of Economic and Statistical Research), and New South Wales (where data are supplied via the Bureau of Crime Statistics and Research). 8 Standardisation of data requires the states and territories to provide data coded according to national classifications and standards. For more information refer to paragraphs 21-22 of the Explanatory Notes. 9 For states and territories other than Victoria data on offences and sentences were obtained from the same source that supplied data on defendants. For Victoria, the offence and sentence data for adjudicated defendants in the Higher Courts were derived from two sources. For defendants with offences proven guilty, the offence and sentence information was derived from the Higher Courts sentencing database. These data were matched to the defendant records obtained from the primary source (courts listing system) for Victorian data. There was incomplete coverage of defendants proven guilty in the Victorian Higher Courts sentencing database, and therefore offence details for some defendants were unavailable. SCOPE Higher Courts 10 The Higher Courts collection includes defendants finalised in the original jurisdiction (see Glossary) of the Supreme and Intermediate Courts in Australia during the reference period 1 July 2004-30 June 2005. Children treated as adults by the courts are included in the collection. Magistrates' Courts 11 The Magistrates' Courts collection includes defendants finalised in the criminal jurisdiction of the Magistrates' Courts. Children treated as adults by the courts are included in the collection. 12 These data include defendants finalised in the Magistrates' Courts for all states and territories except New South Wales where finalised appearances were provided instead of finalised defendants. Therefore, where charges were finalised at different court appearances in the same case for a defendant in New South Wales, these were counted as finalised defendants at each appearance rather than being aggregated as a single finalised defendant at the latest charge finalisation date. Children's Courts 13 Data on defendants finalised in the criminal jurisdiction of the Children's Courts have been included for the first time in this publication. However, due to coverage and other data quality issues they have been labelled as 'experimental' in this issue (see paragraphs 49-50). These data include all defendants finalised in the Children's Courts for all states and territories except New South Wales and the Australian Capital Territory. 14 Data on defendants finalised in the Children's Courts in New South Wales and the Australian Capital Territory were not able to be extracted for inclusion in this issue of the publication. Hence, an Australian total is currently unavailable for Children's Courts. 15 In all states and territories, children aged under the age of 10 years cannot be charged with a criminal offence. The maximum age that defendants are considered a child or juvenile varies between states and territories from under the age of 17 years to under the age of 18 years. Exclusions 16 The Higher, Magistrates' and Children's Courts data exclude cases heard in the criminal jurisdiction of the courts which do not require the adjudication of charges (e.g. bail reviews and applications to amend sentences or penalties). Also excluded are breach of bond cases, appeal cases, tribunal matters and defendants for whom a bench warrant is issued but not executed. 17 The Magistrates' Court data exclude defendants finalised in the Children's Courts, Drug Courts, Electronic Courts, Fine Recovery Units, Family Violence Courts and Indigenous Courts. REFERENCE PERIOD 18 The statistics in this collection relate to defendants who had criminal cases finalised within the Higher, Magistrates' and Children's Courts during the reference period 1 July 2004-30 June 2005. 19 A historical summary of the number of defendants finalised in the Higher Courts for the years 1996-97 through to 2004-05 is provided in table 19. COUNTING UNIT 20 The principal counting unit for the Criminal Courts collection is a defendant. A defendant is a person or organisation against whom one or more criminal charges have been laid and which are heard together as the one unit of work by a court at a particular level. It should be noted that the Criminal Courts collection does not enumerate unique persons or organisations. If a person or organisation is a defendant in a number of criminal cases finalised within the courts during the reference period, this person or organisation will be counted more than once within that reference period. CLASSIFICATIONS 21 The main national classifications used to collect and produce data on defendants in the Criminal Courts are: Method of Finalisation (see Appendix 2) Australian Standard Offence Classification (ASOC) (refer to paragraphs 38-39 of the Explanatory Notes and Appendix 3) National Offence Index (NOI) (refer to paragraphs 40-42 of the Explanatory Notes and Appendix 4) Sentence Type (refer to paragraph 43 of the Explanatory Notes and Appendix 5). 22 The classifications provide a framework for classifying criminal court information for statistical purposes, promoting data that are compiled on a consistent basis across states and territories. The classifications allow for different levels of detail to be recorded depending on the level of detail in the source information. Associated with each classification are coding rules which ensure that the counting of information is consistent across states and territories. NATIONAL CRIMINAL COURTS DATA DICTIONARY 23 A data dictionary is an agreed set of classifications and standards that is accepted as the authoritative source for a particular area of statistics. The National Criminal Courts Data Dictionary, Version 1 has been developed by the National Criminal Courts Statistics Unit (NCCSU) of the ABS in collaboration with key stakeholders. It is a reference document which defines national data items and outlines methods for the use of 27 data elements and concepts that underpin the ABS and Council of Australian Governments (COAG) criminal courts collections. Version 1 of the data dictionary relates to the Higher and Magistrates' Criminal Courts and it is anticipated that Version 2 will extend the scope of the data dictionary to the Children's Criminal Courts. The National Criminal Courts Data Dictionary can be accessed in the Statistical References section of the National Statistical Service web site <http://www.nss.gov.au>. COUNTING METHODOLOGY Method of finalisation 24 Method of finalisation describes how a criminal charge is concluded by a criminal court level. For the purposes of the Criminal Courts collection, one method of finalisation is applied to each defendant within the Higher, Magistrates' and Children's Courts. 25 Prior to 2002-03, a bench warrant issued was considered a method of finalisation. From the 2002-03 reference period, this is no longer considered a method of finalisation for a defendant in the Higher Courts. This is treated as a continuation of a case and will impact the duration of a case i.e. date from initiation to finalisation. This aligns with the Magistrates' Courts and Children's Courts collections which do not include a bench warrant issued as a method of finalisation. Once a bench warrant has been executed, the defendant is regarded as being finalised (by a method of finalisation other than a bench warrant being issued) and is included in data for the relevant reference period in which the defendant is finalised. 26 Defendants who are referred to a Mental Health Review Tribunal (e.g. for determination of fitness for trial) are not considered to be finalised. Transfer between Higher Court levels 27 Defendants who transfer from one Higher Court level to another are considered as initiated only once (in the level they first entered) and finalised only once (from the level they finally left). Transfer between Magistrates' and Higher Court levels 28 Defendants who transfer from the Magistrates' Court level to the Higher Court level are considered as initiated twice (once in each of these levels) and finalised twice (once in each level). Defendants may have some charges finalised in the Magistrates' Courts whilst other charges are committed to the Higher Courts. A defendant in this situation would be counted in the Magistrates' Courts data and the Higher Courts data. Transfers between the Children's Courts and the Magistrates' or Higher Courts 29 Defendants who transfer between the Children's Courts and the Magistrates' or Higher Courts are considered to be initiated and finalised in each court level where they appear. Higher Courts 30 Where a defendant finalised in a Higher Court has multiple charges and these have different methods of finalisation, the defendant method of finalisation code is determined by the following order of precedence: defendant deceased unfit to plead not guilty by reason of mental illness/condition guilty finding by court charge proven n.f.d. guilty plea by defendant acquitted by court charge unproven n.f.d. charge unproven n.e.c. transfer from a Higher Court to a Court of Summary Jurisdiction other transfer between court levels withdrawn by the prosecution other non-adjudicated method of finalisation unknown/not stated. Magistrates' Courts 31 Where a defendant finalised in a Magistrates' Court has multiple charges and these have different methods of finalisation, the defendant method of finalisation code is determined by the following order of precedence: defendant deceased unfit to plead not guilty by reason of mental illness/condition guilty finding by court charge proven n.f.d. guilty plea by defendant guilty ex-parte acquitted by court charge unproven n.f.d. no case to answer at committal charge unproven n.e.c. committed for trial committed n.f.d. committed for sentence non-committed transfer from a Court of Summary Jurisdiction to a Higher Court other transfer between court levels withdrawn by the prosecution other non-adjudicated method of finalisation unknown/not stated. Children's Courts 32 Where a defendant finalised in a Children's Court has multiple charges and these have different methods of finalisation, the defendant method of finalisation code is determined by the following order of precedence: defendant deceased unfit to plead not guilty by reason of mental illness/condition guilty finding by court charge proven n.f.d. guilty plea by defendant guilty ex-parte acquitted by court charge unproven n.f.d. no case to answer at committal charge unproven n.e.c. committed for trial committed n.f.d. committed for sentence transfer from a Children's Court to a Magistrates' or Higher Court n.e.c. other transfer between court levels n.e.c withdrawn by the prosecution other non-adjudicated finalisation n.e.c. unknown/not stated Merging counting units 33 Where a person or organisation is a defendant in more than one case, and their cases are finalised on the same date, in the same court level and in the same court location, their defendant records will be merged and counted as a single defendant record. This merging rule is used for defendants finalised in the Higher, Magistrates' and Children's Courts. Principal offence adjudicated 34 Principal offence is only calculated for adjudicated defendants. Charges considered for the purpose of determining the principal offence are only those charges that have an adjudicated method of finalisation (i.e. where the defendant has pleaded guilty or the court has made a decision as to whether or not the defendant is guilty). Thus, charges that have been transferred to another level of court, together with those that are withdrawn or dealt with by some other non-adjudicated method, are not considered for the purposes of determining the principal offence adjudicated. 35 For a defendant who has a method of finalisation of proven guilty (resulting from a guilty verdict, guilty plea or guilty ex-parte), the principal offence is selected from the charge(s) proven guilty (i.e. acquitted charges are not considered). For a defendant who has a method of finalisation of acquitted, the principal offence is selected from the charge(s) acquitted. 36 Where a defendant has a single proven guilty or acquitted charge, the principal offence is the relevant ASOC code (see paragraphs 38-39) associated with the adjudicated charge. 37 Where a defendant has a method of finalisation of proven guilty with multiple charges proven guilty, or where a defendant has a method of finalisation of acquitted with multiple charges acquitted, the principal offence is selected by applying the National Offence Index (see paragraph 40). The principal offence is determined as the adjudicated charge with the highest ranked ASOC Group in the Index. Where the defendant has an adjudicated charge but is unable to receive an Index ranking (due to missing offence information or the offence mapped to an ASOC code that is not included in the Index) the principal offence is coded to 'not able to be determined'. Australian Standard Offence Classification (ASOC) 38 The ASOC was developed by the ABS for use in the collection and publication of crime and justice statistics. It provides a uniform national classificatory framework for the compilation and comparison of statistics on offences across Australia. 39 Offence data have been coded to the ASOC on the basis of mappings of state/territory legislative codes undertaken by various agencies within those states and territories. The ABS has not undertaken any systematic checks to assess the quality of the ASOC coding for the charges adjudicated in the Criminal Courts. Amendments to the ASOC codes have only been made in very limited cases where erroneous codes were identified as part of the edit checks applied to the final data. National Offence Index (NOI) 40 The National Offence Index (see Appendix 4) is a ranking of all ASOC Groups and selected supplementary ASOC codes (ASOC Divisions and/or ASOC Subdivisions). This ranking is based on the concept of seriousness, with a ranking of 1 relating to the ASOC code containing the most serious offence. In developing this Index, the ranking of offences was analysed using the 2000-01 Higher Courts data. The results indicated that the Index produced principal offence output that aligned with that produced using the 2000-01 Principal Offence rules which were based on actual sentences handed down in the Higher Courts in the 2000-01 reference period. In addition, the Index resulted in significant data quality improvements with the proportion of adjudicated defendants for whom a principal offence was unable to be determined reducing from a national average of 17% in 2000-01 to 3% in 2001-02 using the Index. 41 The assumptions and rules underpinning the NOI, in particular defining 'offence seriousness' and the impact of this definition on the ranking of offences, need to be considered when using the principal offence data in this publication. However, it is important to note that these technical issues are only of practical significance where a choice must be made between output categories (see paragraph 42). For example, although some Sexual assault and related offences are ranked ahead of Illicit drug and related offences, they are unlikely to co-occur. For further information regarding the development of the NOI please refer to Appendix 5 in Criminal Courts, Australia, 2001-02 (cat. no. 4513.0). 42 The principal offence for each adjudicated defendant (i.e. acquitted or proven guilty) is aggregated and published at the ASOC Division level for selected tables, and at the more detailed ASOC Subdivision or Group level (including the ASOC Group of Breach of domestic violence orders) for other tables. Principal sentence 43 Within this publication, defendants who are proven guilty have sentence information reported against them at the defendant level. This is usually, though not necessarily, the sentence associated with the principal offence. A defendant can receive a single sentence for a single offence proven guilty, a single sentence for multiple offences proven guilty, multiple sentences for multiple offences proven guilty and/or multiple sentences assigned to the one offence proven guilty. Where a defendant has multiple sentences, the principal sentence is selected by applying the hierarchy of the Sentence Type Classification (see Appendix 5). DATA COMPARABILITY 44 The Criminal Courts collection has been designed to facilitate comparisons over time and across states and territories through the application of common national statistical standards. However, some legislative and processing differences may limit the degree to which the statistics are comparable across the states and territories. Differences may also arise as a result of other factors, including refinements in data quality procedures and modifications in the systems used to obtain and compile the figures. 45 To ensure that the statistics are as reliable as possible, the ABS has employed a number of measures. A range of edit checks identify data that may contain errors and these are queried and resolved by the ABS in consultation with the relevant state or territory representative. The final data are also checked against other available data sources, such as state and territory court statistics and annual reports produced by the court administration agencies and the Offices of the Directors of Public Prosecutions. 46 Data quality control checks will continue to be reviewed and modified. Data availability and quality will also improve as the states and territories further develop and improve their court operational systems. 47 Reporting of uniform data in relation to the criminal courts in Australia is also enabled by the National Criminal Courts Data Dictionary. CONFIDENTIALITY OF TABULAR DATA 48 Table cells containing small values have been randomly adjusted to avoid releasing confidential information. EXPERIMENTAL DATA 49 The Children's Criminal Court data included in this issue have not been subjected to the same type of validation processes that are applied to the other data presented in this publication and are therefore labelled as 'experimental'. 50 It is expected that the implementation of new information systems in New South Wales and the Australian Capital Territory will facilitate a national Children's Court dataset for the 2006-07 reference period.
